How can glass contribute to performance and energy efficiency?





Solar control glass:


When you need plenty of natural daylight but want to reflect a high proportion of the sun’s heat away from the glass – the answer is solar control glass. It helps reduce the ‘greenhouse effect’ that occurs in summer as rooms heat up to the point that they become unpleasant to be in. With solar control glass, indoor spaces can become brighter and cooler, while uncomfortable glare from the sun can be filtered out. Depending on the climate, it can be more expensive to cool the interior of a building than to heat it. Solar control glass helps minimize the amount of heat energy that penetrates a building, thus helping to limit the use of air conditioning. Large window and facade surfaces can allow plenty of natural light to reach deep into the building’s interior, which can also help reduce the need for artificial lighting.


Glazing for hot and cold climates:


For architectural projects located in warm or moderate climates, a low SHGC or g-value is preferred. The number 2 surface placement of a solar control coating often facilitates the best performance because it partially reflects away incoming solar energy before it can enter the glazing.


In particularly cold climates, a higher SHGC or g-value could be beneficial to allow passive heat gain. The number 3 surface placement of a low-E coating can be ideal by retaining the heat inside the building or home.




Light coming inside the building, as well as coatings and their placement in the glazing, are crucial in supporting occupant comfort. The term ‘spectral selectivity’ is used to address the amount of daylight transmission relative to solar energy blockage. Greater spectral selectivity is achieved when more visible light, and less overall solar energy, is transmitted.


Ways to improve insulating performance of an Insulated Glass Unit (IGU):


The insulating performance of an IGU can be improved in a variety of ways:


• A low-e coating can be used that performs well in reflecting longwave radiation.


• Rather than air, argon gas can be used within the cavity of the IGU to reduce conduction. The cavity width can also be optimized.


• A warm edge spacer can be used to help minimize thermal conductivity at the perimeter of the glazing assembly.


• Another pane of glass can be added so that multiple cavities and coated surfaces can provide increased insulating performance.


Windows can be made more energy efficient by using thermal insulating double- or triple glazing. It means your living or workspace can become more comfortable all year round, with fewer cold spots and drafts, as well as less condensation. The glass can be made to look neutral or beautifully transparent, while giving you the freedom to use larger windows that help flood home and office interiors with natural daylight. All this helps people feel more comfortable.
